According to every dyno test and article I've ever seen, you can't beat the RPM. I have one on my 451, and although Its the only manifold I've tried I'm pretty happy with the crisp throttle response and it pulls to 6500 and above.

The cross over point in torque is about 5,000 rpm for a switch from the RPM to a good single plane, so unless you are going to use a very high stall converter and a fairly large cam, then the RPM.

and from the gear I would say this is mostly a street car.... RPM

If I was buying all new parts I'd use a Mopar M1 4500 intake with a dual pattern Holley 750 DP carb.
Andy, I own a few of your books and hesitate to question anything you reccomend, but a 750 cfm carb on a 470 cube mill with aftermarket heads? Seems pretty conservative. Especially with the M1 single plane intake; it would seem that in order to make the single plane pay off, we would clearly need to take advantage of some upper end HP? Won't 470 cubes outrun the 750 by the time the M1 gets into its wheelhouse??? Mathmatically, at 85% V.E., a 470 needs 750cfm at 6500. This seems to perhaps support your choice, but I'd hate to limit the motor at the entry point like that, knowing that an 850 will run great and give you more ability to breath and make HP up top. (???)

OP seems to have more of a street engine than a race engine so the 750 would work better 90% of the time.
If the car spends all of its time on the street then I'd use a Performer RPM with a 800 cfm Edelbrock carb. I ran that setup on my low deck 470 and made enough power to run mid-11's in my '65 Coronet. (with HP manifolds)

RPM on my lo deck 512 Works great and pulls to 6000ish with Stealth heads.
